How is net salary calculated in Tonga?
In Tonga, net salary is calculated by subtracting social security contributions (TSDF (Tonga Salary Deduction Fund)) and income tax (ITIS (Income Tax on Salary, MoF) 2024) from the annual gross salary.
ITIS (Income Tax on Salary, MoF) 2024 uses a progressive scale. Rates range from 0 % for the lowest incomes to 20 % for the highest. Only the portion of income that falls within each bracket is taxed at that rate, never the full salary.
TSDF (Tonga Salary Deduction Fund) contributions amount to approximately 5 % of gross salary, funding the pension, healthcare and other social benefits available to employees in Tonga.
This calculator uses official data from Ministry of Finance of Tonga for 2026. Results are indicative; for exact calculations or specific situations (personal deductions, special regimes) consult a tax adviser or the country's tax authority.
Tonga applies a flat 20% rate on wages exceeding TOP 7,920/year (TOP 152/week). The Tongan paʻanga (TOP) is the official currency. The employee contributes 5% to the TSDF (pension); the employer adds 5%.
